Atrial Fibrillation Risks

Risks Of Atrial Fibrillation

If you suffer from atrial fibrillation, then it is very important for you to make sure that you receive the proper treatment. There are a number of complications that can result if atrial fibrillation is not treated. Below is a list of some of the possible complications of atrial fibrillation:

Atrial Fibrillation Risks


Blood clots can develop if the blood starts to pool inside of the heart’s upper chambers. If a blood clot forms inside of the heart, then it can potentially travel to the brain. A stroke can result if blood flow to the brain is blocked. Older people with atrial fibrillation are more likely to have a stroke. The risk of stroke is also higher in people who have another chronic condition, such as diabetes or high blood pressure. It is estimated that 15 out of 100 strokes are caused by atrial fibrillation. Furthermore, people who have atrial fibrillation are four to five times more likely to have a stroke.

Some of the symptoms of muscle weakness on one side of the body, speech problems, numbness in the face and drooping in the face. Keep in mind that many people have silent strokes and do not even know it.


If atrial fibrillation is not treated, then it can cause the heart to beat too fast. Over time, this can weaken the heart muscle and lead to a condition called cardiomyopathy. Cardiomyopathy often leads to heart failure. Heart failure occurs when the heart is unable to pump enough blood to meet the demands of the body. The right, left or both sides of the body can be affected by this condition. Heart failure can result in death.

Alzheimer’s Disease

There has been evidence to suggest that atrial fibrillation can increase the risk of Alzheimer’s disease. There was a study done that involved 5,000 people who were over the age of 65. The study found that people who had atrial fibrillation had a tendency to suffer from cognitive decline at a younger age.

The researchers in the study could not determine exactly why people who have atrial fibrillation are more likely to develop Alzheimer’s disease. However, they did find that both conditions have similar risk factors. They also believe that treating both conditions will help improve the patient’s prognosis.
